heh-heh. Wow...way to come at it, HIB. My wife still has trouble understanding this concept and no matter how much I explain it to her, she doesn't get it either.
You could have a 100" big screen, and you're still only getting a 1920x1080 resolution (1080P). What you see on that 100" TV, from left to right and top to bottom, are EXACTLY what you'd see on a 24" 1080P monitor. You get no further viewing angle/depth/width...whatever you want to call it...just because you're TV is bigger. You have the same exact number of pixels and thus the same image on either screen - a TV just has bigger pixels and the bigger they get, the more distorted your image will be.
EyeFinity, on the other hand, with three 1080P monitors (like my setup) is THREE 1080P monitors. The center monitor has what you'd normally see on your single monitor or your big TV. The side monitors, on the other hand, introduce peripheral vision on either side. It's NOT a single 1920x1080 view - it's 5760x1080. Yes...you have about 3/4" of bezel in between the monitors - whooptie doo. It has never affected me in any game I play. In fact, in the 10.3 drivers coming out next month, you'll be able to tell the Catalyst drivers how much bezel you have and it will adjust the image to "hide" that portion of the image behind the bezel instead of stretching it (maybe not the right term) across the monitors so you have a huge gap between them.
So, I'd say Paperfox and Anime are quite right and you, my friend, need to learn some etiquette and actually use EyeFinity before you spout off something you don't know about. I'd highly recommend looking at some YouTube videos of EyeFinity in action before you judge it being a POS. I, personally, can't imagine EVER gaming on a single screen again, regardless of how big it is.
